Description

Technical Field

[0001] The present invention relates to the technical field of optical lenses, and in particular to a multi-mode lens switching mechanism and an optical lens. Background Art

[0002] As a component used for optical imaging, the optical lens is an important component of the machine vision system and plays a key role in image quality. The optical lens is usually composed of multiple lenses and a lens barrel. In some application scenarios, the lens needs to be rotated or even cut in or out of the optical lens. This requires the structure of the optical lens to be readjusted. However, the following problems often occur during the adjustment process:

[0003] When switching lenses in or out of a lens barrel, the entire lens is usually switched. In particular, when switching convex lenses, the entire convex lens is usually directly replaced. However, it is not possible to fine-tune the focal length of the convex lens. For special purposes, the focal length of the corresponding convex lens needs to be adjusted, but the existing technology cannot fine-tune a single convex lens.

[0004] Secondly, in the process of switching convex lenses, a combination of multiple types of lenses is usually required. During this switching process, the lenses will inevitably be bonded. Conventional lens bonding uses contact alignment or sliding alignment between lenses. However, for products such as lenses, conventional sliding alignment can easily cause lens scratches. Therefore, alignment is first adopted and then close bonding is adopted. However, this method requires that the lenses be bonded slowly during the bonding process to avoid damage to the lenses.

[0005] To this end, we designed a multi-mode lens switching mechanism and optical lens. Summary of the Invention

[0006] The purpose of the present invention is to solve the problem that in the prior art, the switching of convex lenses usually involves directly replacing the entire convex lens as a whole, but it is impossible to fine-tune the focal length of the convex lens. For special purposes, the focal length of the corresponding convex lens needs to be adjusted. A multi-mode lens switching mechanism and optical lens are proposed.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A multi-mode lens switching mechanism includes a first lens barrel and a second lens barrel, the first lens barrel and the second lens barrel are coaxially arranged and connected by a connecting frame, two mounting rotating frames are rotated between the first lens barrel and the second lens barrel, the mounting rotating frame rotates between the first lens barrel and the second lens barrel through a fixed shaft, a convex lens assembly is installed on the mounting rotating frame, the convex lens assembly includes a first convex lens and a second convex lens, a positioning mechanism is provided on the fixed shaft for driving the mounting rotating frame to rotate and position, and a propulsion and pressure relief assembly is also provided on the fixed shaft for pushing the convex lens assembly on the mounting rotating frame to fit.

[0009] Preferably, the fixed shaft is fixed to the outer side walls of the first lens barrel and the second lens barrel directly below the connecting frame through a pillow block, and the rotating frame is installed to rotate coaxially on the fixed shaft.

[0010] Preferably, installing the turret comprises:

[0011] A propulsion ring, the propulsion ring is coaxially sleeved on the outer side wall of the fixed shaft;

[0012] The mounting ring is provided in multiple configurations and is equidistantly arranged on the outer side wall of the propulsion ring in a circumferential manner, and the mounting ring and the propulsion ring are connected via a connecting frame.

[0013] Preferably, the first convex lens and the second convex lens are both convex lenses with a curved surface on one side and a flat surface on the other side, and the first convex lens and the second convex lens have the same flat surface radius and different curvatures of the curved surfaces.

[0014] Preferably, the positioning mechanism comprises:

[0015] A rotating ring is coaxially sleeved on the outer wall of the fixed shaft, and the rotating ring rotates on the outer wall of the fixed shaft through the first ring groove and the ring block;

[0016] The plug rod slides radially through the rotating ring through the through hole, and the plug rod is reset and retracted in the through hole by a reset spring, and a slot corresponding to the position of the mounting ring is opened on the outer wall of the fixed shaft.

[0017] Preferably, a plurality of connecting rods are inserted through the rotating ring, one end of the connecting rod is fixedly connected to the propulsion ring, and the other end of the connecting rod is fixed with a magnet ring sleeved on the outer wall of the fixed shaft.

[0018] Preferably, both ends of the fixed shaft are provided with electromagnetic generators for attracting and repelling the magnet ring.

[0019] Preferably, a sealing bag is provided between the two propulsion rings and filled with non-Newtonian liquid. Second ring grooves are provided at opposite ends of the two propulsion rings. An elastic plate is placed on the sealing bag, and both ends of the elastic plate slide in the second ring groove through end blocks.

[0020] Preferably, a placement groove is provided on the mounting ring, and the first convex lens and the second convex lens are placed in the placement groove. The outer side walls of the first convex lens and the second convex lens are provided with a push plate, and the push plate slides telescopically on the mounting ring through the spring groove. The spring groove is provided with a compression spring that pushes the first convex lens and the second convex lens to protrude out of the placement groove.

[0021] An optical lens, a convex lens assembly includes an optical lens.

[0022] The beneficial effects of the present invention are:

[0023] 1. In the present invention, when the mounting ring is driven to rotate together with the propulsion ring, the mounting ring will stop positioning after it rotates to a position between the first lens barrel and the second lens barrel and is coaxially arranged. At this time, the mounting ring is coaxially arranged with the first lens barrel and the second lens barrel. Therefore, as the propulsion ring rotates, multiple mounting rings can be rotated to a position between the first lens barrel and the second lens barrel. In this way, mounting rings with different convex lens assemblies installed can be combined, among which different convex lenses can be selected, so that the planes of the convex lenses are fitted together to form a matching convex lens, thereby realizing the switching of the convex lenses, and finally changing the focal length to meet the required convex lens requirements, thereby forming a convex lens combination with different focal lengths.

[0024] 2. In the present invention, since the first convex lens and the second convex lens protrude from the mounting groove, the final effect during the process of the advancing rings approaching each other is that the two mounting rings are close to each other. Therefore, during the process of the two mounting rings approaching each other, the first convex lens and the second convex lens protruding from the mounting groove will be the first to be close to each other. At the same time, since the sealing bag containing the non-Newtonian liquid can play a buffering role in the mutual approach of the first convex lens and the second convex lens, the collision and bumping phenomenon during the convex lens combination process is avoided. If the first convex lens and the second convex lens do not have the protruding mounting groove, there will be a gap between the first convex lens and the second convex lens after the two mounting rings approach each other, which will affect the light of optical observation.

[0037] Reference Figures 1-9 A multi-mode lens switching mechanism includes a first lens barrel 1 and a second lens barrel 2. The first lens barrel 1 and the second lens barrel 2 are coaxially arranged and connected by a connecting frame 3. Flat glass 4 is installed at the opposite ends of the first lens barrel 1 and the second lens barrel 2. Therefore, the first lens barrel 1 and the second lens barrel 2 are coaxially arranged to provide linear observation conditions for optical observation of the lens.

[0038] There are two mounting rotating frames 7 that rotate between the first lens barrel 1 and the second lens barrel 2. The mounting rotating frame 7 rotates between the first lens barrel 1 and the second lens barrel 2 through the fixed shaft 5. It should be noted that the mounting rotating frame 7 rotates between the first lens barrel 1 and the second lens barrel 2, which plays a role in switching the type of observation lens. The fixed shaft 5 is fixed to the outer side walls of the first lens barrel 1 and the second lens barrel 2 directly below the connecting frame 3 through the pillow block 6. The mounting rotating frame 7 rotates coaxially on the fixed shaft 5, thereby providing support for the rotation of the mounting rotating frame 7, allowing the rotation of the mounting rotating frame 7 to operate stably.

[0039] Reference Figure 1 and Figure 2 The mounting rotating frame 7 in the state includes a propulsion ring 71 and a mounting ring 73. The propulsion ring 71 is coaxially sleeved on the outer wall of the fixed shaft 5. The mounting ring 73 is provided in multiple configurations. Therefore, when the propulsion ring 71 is driven to rotate, the mounting ring 73 can be driven to rotate together.

[0040] The mounting rings 73 are circumferentially and equidistantly arranged on the outer wall of the propulsion ring 71, and the mounting rings 73 are connected to the propulsion ring 71 by a connecting frame 72. It should be noted that when the propulsion ring 71 rotates and drives the mounting ring 73 to rotate together, the mounting ring 73 will stop when it rotates to a position between the first lens barrel 1 and the second lens barrel 2. At this time, the mounting ring 73 is coaxial with the first lens barrel 1 and the second lens barrel 2. Therefore, as the propulsion ring 71 rotates, multiple mounting rings 73 can be rotated to a position between the first lens barrel 1 and the second lens barrel 2. In this way, a convex lens combination with different focal lengths can be formed by combining the mounting rings 73 with different convex lens assemblies. The convex lens assembly is installed on the mounting rotating frame 7.

[0041] The first convex lens 8 and the second convex lens 9 are both convex lenses with a curved surface on one side and a flat surface on the other side. The first convex lens 8 and the second convex lens 9 have the same plane radius and different curvatures of the curved surfaces. Therefore, different convex lenses are selected so that the planes of the convex lenses fit together to form a matched convex lens, thereby realizing the switching of the convex lenses and finally changing the focal length to meet the required convex lens requirements.

[0042] The convex lens assembly includes a first convex lens 8 and a second convex lens 9, referring to Figure 9State diagram, when the two first convex lenses 8 are flatly attached to each other to form a matched convex lens, the focal length at this time is F2. When one of the mounting rotating frames 7 is rotated, one of the two first convex lenses 8 originally in the attached state is separated, and the second convex lens 9 is attached to the previous first convex lens 8, and the focal length at this time is F1. Since the curvature of the curved surface of the first convex lens 8 is greater than the curvature of the curved surface of the second convex lens 9, the focal length F1 is greater than the focal length F2. Therefore, the convex lens assembly is selected and switched according to different needs, and then the lens switching is realized to change the focal length, and finally the required convex lens optical effect is achieved.

[0043] A positioning mechanism is provided on the fixed shaft 5 for driving the mounting rotating frame 7 to rotate and position. The positioning mechanism is used to position the rotating mounting frame 7 after rotation, so that the mounting ring 73 is rotated to a position between the first lens barrel 1 and the second lens barrel 2 and positioned. At this time, the mounting ring 73, the first lens barrel 1 and the second lens barrel 2 are coaxially arranged. The positioning mechanism serves to fix the two mounting rings 73 to prevent the mounting rings 73 from moving during use, thereby ensuring that the convex lens assembly in the mounting ring 73 is stable.

[0044] The positioning mechanism includes a rotating ring 10, which is coaxially sleeved on the outer wall of the fixed shaft 5, and the rotating ring 10 rotates on the outer wall of the fixed shaft 5 through the first ring groove 16 and the ring block 17, so that the rotating ring 10 can stably rotate on the outer wall of the fixed shaft 5, wherein a plurality of connecting rods 13 are inserted through the rotating ring 10, and one end of the connecting rod 13 is fixedly connected to the propulsion ring 71. Therefore, when the rotating ring 10 is turned, the rotating ring 10 is rotated on the fixed shaft 5. Since the connecting rod 13 is inserted through the rotating ring 10 and the connecting rod 13 is connected to the propulsion ring 71, the propulsion ring 71 is rotated synchronously with the rotating ring 10 during the rotation process, and finally the rotation of the mounting ring 73 is switched between the first lens barrel 1 and the second lens barrel 2.

[0045] Since different types of convex lenses are mounted on the multiple mounting rings 73 provided on the propulsion ring 71 , the two mounting rings 73 can be combined in a variety of ways to achieve the effect of forming convex lenses with different focal lengths.

[0046] Reference Figure 5 and Figure 6State, the positioning mechanism also includes an insertion rod 14, which slides radially through the rotating ring 10 through the through hole, and the insertion rod 14 is reset and retracted in the through hole by the return spring 15. Therefore, before toggling the rotating ring 10, it is necessary to first pull the insertion rod 14 upward to disengage the insertion rod 14 from the slot 18, that is, to release the positioning effect of the rotating ring 10 and the outer wall of the fixed shaft 5, and then during the rotation process, release the insertion rod 14. At this time, the insertion rod 14 is against the outer wall of the fixed shaft 5 under the action of the return spring 15, and then continue to toggle the rotating ring 10. When the insertion rod 14 moves to the top of the next slot 18, the insertion rod 14 will be reinserted in the next slot 18 under the action of the return spring 15, thereby completing the re-positioning of the rotating ring 10.

[0047] The outer wall of the fixed shaft 5 is provided with a slot 18 corresponding to the position of the mounting ring 73, that is, the vertical plane where the slot 18 and the mounting ring 73 are located is parallel to the axis of the fixed shaft 5. Therefore, under the rotation of the rotating ring 10 and the insertion of the insertion rod 14 in the slot 18, the mounting ring 73 can be located between the first lens barrel 1 and the second lens barrel 2, so that the mounting ring 73 is coaxially arranged between the first lens barrel 1 and the second lens barrel 2.

[0048] When the two mounting rings 73 are switched, the two mounting rings 73 and the convex lens assembly are fixed between the first lens barrel 1 and the second lens barrel 2. In order to ensure the accuracy of visual observation of the convex lens assembly, it is necessary to promptly fit the two originally separated convex lens assemblies together to form a new matching convex lens. Therefore, the first convex lens 8 and the second convex lens 9 originally coaxially arranged are plane-fitted. Therefore, the first convex lens 8 and the second convex lens 9 need to be close to each other. The other end of the connecting rod 13 is fixed with a magnet ring 12 sleeved on the outer wall of the fixed shaft 5, and both ends of the fixed shaft 5 are provided with an electromagnetic generator 11 that attracts and repels the magnet ring 12. The electromagnetic generator 11 generates a magnetic field by passing current through a spiral coil. This device is a prior art and will not be elaborated on here. Therefore, by turning on the electromagnetic generator 11 and allowing the electromagnetic generator 11 to generate the same magnetic field as the magnet ring 12, the magnet rings 12 at both ends of the fixed shaft 5 will be pushed close to each other through the connecting rod 13 with the propulsion ring 71, thereby completing the close fitting of the convex lens assemblies.

[0049] The fixed shaft 5 is also provided with a push-and-hold assembly for pushing the convex lens assembly on the rotating frame 7 to fit together. The push-and-hold assembly is used to effectively buffer the convex lens assemblies approaching each other to prevent the two convex lens assemblies from being damaged by the force of colliding with each other during the pushing process. Therefore, it is necessary to slowly push the convex lens assemblies approaching each other, so that the two convex lens assemblies can finally achieve non-collision contact.

[0050] Reference Figure 7 and Figure 8In this state, a sealing bag 23 is provided between the two propulsion rings 71, and the sealing bag 23 is filled with non-Newtonian liquid. Therefore, when the two propulsion rings 71 suddenly approach each other, the non-Newtonian liquid in the sealing bag 23 will be squeezed first. This not only can buffer the approach of the two propulsion rings 71 to each other, but also slow down the propulsion of the propulsion rings 71, and then allow the two propulsion rings 71 to slowly squeeze the non-Newtonian liquid in the sealing bag 23, and finally allow the two propulsion rings 71 to slowly approach each other, and finally achieve the slow approach of the propulsion rings 71, thereby protecting the convex lens assembly from collision.

[0051] The two propulsion rings 71 are provided with a second annular groove 26 at the opposite ends, and an elastic plate 24 is mounted on the sealing bag 23, and the two ends of the elastic plate 24 slide in the second annular groove 26 through the end blocks 25. When the convex lens assembly needs to be rotated and switched, the convex lens assemblies that were originally fitted together need to be separated first. It should be noted that the setting here not only does not hinder the rotation of the propulsion ring 71 on the fixed shaft 5, but also allows the electromagnetic generator 11 to face the opposite magnetic field of the magnet ring 12, which will drive the magnet rings 12 at both ends of the fixed shaft 5 to move away from each other with the propulsion ring 71 through the connecting rod 13.

[0052] Furthermore, when the propulsion rings 71 move away from each other, the elastic plate 24 presses the propped-up sealing bag 23 to return the non-Newtonian liquid in the sealing bag 23 to its original position, thereby facilitating the next buffering and deceleration.

[0053] Reference Figure 3 and Figure 4 State, the propulsion and pressure relief assembly includes a placement groove 19, which is arranged on the mounting ring 73, and the first convex lens 8 and the second convex lens 9 are placed in the placement groove 19. The outer side walls of the first convex lens 8 and the second convex lens 9 are both provided with a propulsion plate 22, and the propulsion plate 22 is telescopically slidable on the mounting ring 73 through the spring groove 20, so that the first convex lens 8 and the second convex lens 9 can slide stably on the mounting ring 73 through the propulsion plate 22 and the spring groove 20.

[0054] A compression spring 21 is provided in the spring groove 20 to push the first convex lens 8 and the second convex lens 9 out of the placement groove 19. It should be noted that since the first convex lens 8 and the second convex lens 9 protrude out of the placement groove 19, the final effect in the process of the propulsion rings 71 approaching each other is that the two mounting rings 73 are close to each other. Therefore, in the process of the two mounting rings 73 approaching each other, the first convex lens 8 and the second convex lens 9 protruding out of the placement groove 19 will be close to each other first. If the first convex lens 8 and the second convex lens 9 do not protrude out of the placement groove 19, there will be a gap between the first convex lens 8 and the second convex lens 9 after the two mounting rings 73 approach each other and press together, which will affect the light of optical observation.

[0055] An optical lens, a convex lens assembly includes an optical lens, the optical lens is a convex lens of various specifications, and the optical lens is a convex lens with a curved surface on one side and a flat surface on the other side.

[0056] The working principle of the present invention is as follows:

[0057] The first lens barrel 1 and the second lens barrel 2 are connected by a connecting frame 3, so the first lens barrel 1 and the second lens barrel 2 are coaxially arranged to provide linear observation conditions for optical observation of the lens. Therefore, when the lens needs to be adjusted, it is necessary to first pull up the insertion rod 14 to disengage the insertion rod 14 from the slot 18, that is, to release the positioning effect of the rotating ring 10 and the outer wall of the fixed shaft 5, and then release the insertion rod 14 during the rotation process. At this time, the insertion rod 14 is against the outer wall of the fixed shaft 5 under the action of the return spring 15, and then continue to turn the rotating ring 10. When the insertion rod 14 moves to the top of the next slot 18, the insertion rod 14 will be reinserted into the next slot 18 under the action of the return spring 15, thereby completing the re-positioning of the rotating ring 10.

[0058] Then, by turning on the electromagnetic generator 11 and allowing the electromagnetic generator 11 to generate the same magnetic field as the magnet ring 12, the magnet rings 12 at both ends of the fixed shaft 5 will be pushed closer to each other through the connecting rod 13 with the propulsion ring 71, thereby completing the convex lens assemblies to be close to each other and fit together. The two convex lens assemblies are subjected to the force of mutual collision, causing the convex lens assemblies to be damaged, so it is necessary to slowly push the convex lens assemblies that are close to each other, and finally make the two convex lens assemblies achieve non-collision contact.

[0059] When the two propulsion rings 71 suddenly approach each other, they will first squeeze the non-Newtonian liquid in the sealing bag 23. This not only cushions the approach of the two propulsion rings 71, but also slows down the propulsion of the propulsion rings 71. Then, the two propulsion rings 71 slowly squeeze the non-Newtonian liquid in the sealing bag 23, and finally the two propulsion rings 71 slowly approach each other, thereby achieving a slow approach of the propulsion rings 71 and protecting the convex lens assembly from collision.

[0060] The first convex lens 8 and the second convex lens 9 protrude from the mounting groove 19, so the final effect in the process of the propulsion rings 71 approaching each other is that the two mounting rings 73 approach each other tightly. Therefore, in the process of the two mounting rings 73 approaching each other, the first convex lens 8 and the second convex lens 9 protruding from the mounting groove 19 will be tightly attached first. If the first convex lens 8 and the second convex lens 9 do not protrude from the mounting groove 19, there will be a gap between the first convex lens 8 and the second convex lens 9 after the two mounting rings 73 approach each other tightly, which will affect the light of optical observation.

Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
